❑ You cannot create two classifiers that have the same settings.
There can be only one classifier for any given type of traffic flow.
❑ The switch can store up to 256 classifiers. However, the maximum
number of classifiers that you can assign to access control lists and
QoS policies at any one time will be from 14 to 127. The number
depends on several factors, such as the number of ports to which
the classifiers are assigned and the types of criteria defined in the
classifiers.
❑ You cannot modify a classifier if it belongs to an ACL or QoS policy
that is assigned to a port. You must first remove the port
assignments from the ACL or policy and reassign them after you
modify the classifier.
❑ You cannot delete a classifier if it is assigned to an ACL or QoS
policy. In order to delete a classifier, you must first remove it from
its ACL and QoS policies.
